cleaned my throttle body, with cleaner and cleaned the entire body. even the gray stuff.

after installing it car runs weird but no boost leaks in throttle after I installed it

is there a spray i need to apply to the throttle body I guess to seal the extra air coming pass the butterfly? want to take care of this so my car can run normal

or should I adjust the tables to compensate for the extra air

need some help

Drive it some and let the ecu readjust. If it doesn't fix itself, then worry about adjusting the tune.

I did the same thing, I wiped that tb clean! afterwards, found out about the sealer. I had issues for a while, even bought a boomba throttlebody, as it was cheaper than a stocker. was good until smog. took a chance and re-installed the old throttle body, and it felt ok again. steps I did after the install, I did a koeo ( key on, engine off relearn procedure), and the idle has been rock solid for 3 years. no adding goop or anything. turn key to run position, but don't start the car, then turn the key back to off. do that a total of 3 times. on the third time, start the car and run until full operating temp. before moving the car. you should do it with the ac off and redo the procedure with a/c on to compensate. this worked for me. good luck brother.

I guess you didnt read my thread correctly, thanks for thread considering I already rebuilt my throttle body using this thread.

And I cant find this spray so i am looking for a replica

Molykote 321 dry film lubricant" which I was not able to purchase due to some type of restriction... however If you cannot find that, this product is a suitable replacement:

I made the same mistake cleaning off the molybdenum dry lubricant. I also live in a state the molykote is restricted for sale. I wound up using something specifically for throttle bottles... Tomei throttle coat. The one vendor i found that carried it had to order it from japan and took 2 weeks to get it. There was also a thread where someone used another brand of a molybdenum spray that wasn't restricted for sale and worked well on the throttle bodies.

Ill just go on google then,

So you just spray it on, or do you apply a few coats

The cap comes with a brush and you just brush it on. Brush on as many coats as you need until you dont see light through the butterfly valve.

I cleaned off my tb and plate with brake parts cleaner and a scrub brush then ported and polished the intake side of it. I never sprayed any kind of lube on it and it runs fine. Should I find some of this TB spray and spray it?

So you rebuilt the TB rt? I am almost certain it isnt lube, likely 'other" issues are the buttlerfly not being exactly centered and therefore open more then it was when you took it off or the TPS isnt exactly back where it should be or seals not positioned correctly and leaking--- my bet is on one or all of these.

Read the thread. You can use any moly spray.

Tps is ar 13.33%
No leaks
Butterfly is centered
I think its the spray that cane to the conclusion now I have to look

That simply isn't true. I went through many moly sprays and did not find one that was able to ship in my state that sufficiently sealed the throttle plate. The problem is most of the sprays dont include enough molydenum in them.

If you only cleaned off the intake side and didn't clean it from behind you would have an issue since the lube is behind the throttle plate. Also some throttle plates seal better than others so some people will have no issue after cleaning the plate and some people will have huge issues.

While i was having my issue i read a thread on a gtr forum which eric hsu from xs engineering posted he used testers model paint and used a very thin coat around where the butterly meets the throttle body walls and it did the trick. I had other issues with my tb at the time so could not confirm it if worked
